Accustic Arts : AMP III ULTRA POWER
Premium Dual-Mono Power Amplifier
Our statement in terms of audiophile power amplifiers
The Accustic Arts Amp III is a reference power amplifier, offering effortless power (2 x 600W into 8 ohms, 2 x 1000W into 4 ohms) with a high end design that matches perfectly with an Accustic Arts pre amplifier and any other fine hi-fi. One of the best large power amps we've ever heard that surpasses the performance of the already stunning Amp II Mk2.
In contrast to the Amp 2 MkII, the Amp III features double the MOS-FET output transistors, a more powerful transformer, and massive rated power outputs perfect for driving any large or difficult to drive speakers.
